This release also incorporates all bug fixes and changes made in previous NDB Cluster releases, as well as all bug fixes and feature changes which were added in mainline MySQL 5.6 through MySQL 5.6.45 (see Changes in MySQL 5.6.45 (2019-07-22, General Availability)).
The requestInfo fields for the long and short
forms of the LQHKEYREQ signal had different
definitions; bits used for the key length in the short version
were reused for flags in the long version, since the key length
is implicit in the section length of the long version of the
signal but it was possible for long LQHKEYREQ
signals to contain a keylength in these same bits, which could
be misinterpreted by the receiving local query handler,
potentially leading to errors. Checks have now been implemented
to make sure that this no longer happens.
